What rigs_actOnRig does on Genesis
AI agents invoke rigs_actOnRig to trigger actions in Genesis. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
| Parameter | Type | Required | Description |
|---|---|---|---|
id | string | Yes | The Rig's id (an Omega deployment UUID) |
body | object | Yes | |
idempotency_key | string | — | Optional stable key; with it a retry returns the original result |
Parameters from the server's own tool schema.

rigs_actOnRig stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
